Eigenfactor: A free and searchable database, Eigenfactor covers the natural and social sciences and "also lists newsprint, PhD theses, popular magazines and more." "It ranks the influence of journals much as Google’s PageRank algorithm ranks the influence of web pages. By this approach, journals are considered to be influential if they are cited often by other influential journals." The Eigenfactor is now included in Journal Citation Reports.
